Data Scientist

Research Branch, Ministry of Social Development & Poverty Reduction, Province of British Columbia

Apr 2020 – Present Victoria, BC, Canada
Responsibilites:

  • Statistical modelling, hypothesis testing, and machine learning with R & SAS.
  • Studying the recent history of government service utilization in the Downtown Eastside neighbourhood of Vancouver to characterize (mental) health, socioeconomic, and demographic relationships with poverty and homelessness. You can learn more about this data innovation program project here.
  • In partnership with the BC Centre for Disease Control, I am leading a team of 4 researchers seeking to use unsupervised machine learning and statistical models to identify determinants of overdose risk among British Columbians struggling with opioid addiction.
  • Advising executives on the use of quantitative methods to address strategic knowledge gaps.
  • Developing an R package, “elucidate”, to make data analysis easier for scientific researchers.
  • Querying, modifying, and constructing relational databases using SQL and Git Bash.
  • Cleaning, transforming, and processing high dimensional data (millions of rows) to facilitate reproducible analysis.
 
 
 
 
 

Data Science Fellow

Office of the Chief Information Officer, Ministry of Citizen’s Services, Province of British Columbia

May 2019 – Apr 2020 Victoria, BC, Canada
Responsibilites:

  • Applied time-series regression models to simultaneously evaluate the effects of multiple social assistance policies and economic recessions on social assistance program utilization and estimate the costs of service delivery.
  • Designed and began to conduct a team research project examining the government service utilization history of Vancouver.
  • Created an R package, “elucidate”, to make exploratory data analysis easier for researchers.
  • Queried, modified, and constructed relational database tables using SQL and Git Bash.
  • Cleaned, transformed, and processed high dimensional data (millions of rows) to facilitate reproducible analysis in secure analytics environments.
 
 
 
 
 

Postdoctoral Fellow in Neuroscience

Division of Medical Sciences, University of Victoria

Oct 2018 – Apr 2019 Victoria, BC, Canada
Responsibilities:

  • Statistical modelling, hypothesis testing, and machine learning with R.
  • Cleaning, transforming, and processing high dimensional health data to facilitate reproducible analysis.
  • Discovering health-related patterns and predictors in experimental and epidemiological data.
  • Uncovered novel therapeutic targets for post-concussion treatment via differential expression analysis of proteomics data.
  • Leveraged multiple correspondence analysis and clustering to identify disease comorbidity patterns using questionnaire data from over 50,000 participants in the Canadian Longitudinal Study on Aging (CLSA; https://www.clsa-elcv.ca/).
  • Predicted concussion status with over 95% test accuracy based on demographic information, clinical history, and cognitive evaluations from hundreds of patients with a decision tree and used permutation techniques to characterize concussion-related behavioural impairments many months after a traumatic brain injury.
